Grundfos 3 SQF-2: Solar-Powered Water From Deep Wells
If your well is deep and the power lines are far away, getting water up to the surface is usually the hard part. The Grundfos 3 SQF-2 SQFlex pump runs straight off solar panels or AC power and lifts water up to 395 ft. It is a 3-inch helical rotor pump made for high head and modest flow, so it suits homesteads, cabins, livestock tanks and remote properties.
Why You'll Love The Grundfos 3 SQF-2 SQFlex Pump
Runs on almost any power source. The built-in electronics accept 30 to 300 VDC or 90 to 240 VAC at 50/60 Hz. Wire it to solar modules, a wind turbine, batteries or a generator, and you are not tied to one setup forever.
Gets the most out of every sunbeam. Built-in MPPT tracks the best operating point of your solar array as the light changes. That means more water pumped on cloudy mornings and late afternoons, not just at midday.
Lifts water from deep wells. With up to 395 ft of head and flow up to 3 GPM, it is built to move water a long way up, steadily, all day. That is ideal for filling a storage tank while the sun is out.
Protects itself. A water level electrode on the cable gives dry-running protection, and the motor guards against over and under voltage. Less babysitting for you, and a longer life for the pump.
Your life, with the Grundfos 3 SQF-2 SQFlex Pump
The sun comes up over the property and the pump quietly starts working. By lunchtime the stock tank is topped up and the house cistern is full. No fuel to haul, no generator to start, and no power bill for pumping.
When the weather turns, you can switch it over to AC power and keep the water flowing.
The Grundfos 3 SQF-2 SQFlex Pump in a nutshell
Helical rotor design for high head
A hard-chromium plated stainless steel rotor turns inside a double helical elastic stator. This positive displacement design is made for high heads and small flows, which is exactly what a deep residential or livestock well needs.
Permanent-magnet SQFlex motor
The 304 stainless steel MSF 3 motor runs from 500 to 3,600 rpm depending on available power, with a maximum input of 1,400 W and 8.4 A. It adjusts its speed to match the power available from your panels.
Complete, ready-to-install unit
The Grundfos 3 SQF-2 comes as a complete unit with the motor, a 6 ft cable with water level electrode and socket, and a cable guard.
Expandable controls
Pair it with the Grundfos CU 200 control unit (sold separately) to add a float or level switch in your tank, so the pump stops when the tank is full.
